Property Description

map of nature centerWehr Nature Center and Whitnall Park contain a unique set of diverse natural environments in a familiar suburban setting. We think there's no better place to be reminded that there is astounding biodiversity in your own backyard, and how important that biodiversity is to all of us.  Wehr Nature Center is also fully accessible, making this an event for everyone!

Interesting Discoveries

  • Arisaema dracontium – Green dragon (not common in this area)
  • Ginkgo biloba – The ginko tree is native to China. It’s widely used as a street tree (there are plenty in Milwaukee), but usually only males are planted as the females produce fruit that smell terrible when they break open. How it came to be where it is a bit of a mystery.
  • Pleuroloma flavipes millipede – First time this species has been documented in Milwaukee in more than 100 years. It’s hard to tell from this how scarce or common the millipede actually is; chances are that nobody spent time looking for it, but also it’s been a regular feature of the Wehr Nature Center grounds (and building!) for years and they didn’t know what they had.

Two lepidoptera of note:

  • Cabera quadrifasciaria - Four-lined Cabera moth
  • Ponometia binocula - Prairie bird-dropping moth

These are both moths that require good quality prairie habitat to complete their lifecycle, which is exciting to find in a prairie restoration like Wehr’s.
